Resumen
The lacrimal fluid is characterized by a mixture of molecules from proteins, lipids, metabolites among others, which play an important role in the pathophysiology of different diseases, for which it has been of great interest in the scientific community for the search of biomarkers and development of therapeutic strategies in systemic and eye diseases. The lower invasiveness and risk when obtaining the tear, makes it an interesting sample compared to some bodily fluids that can be much more expensive and annoying to obtain. The above has been demonstrated through various studies in which they suggest different strategies to obtain the sample and its subsequent analysis using techniques of molecular and cellular biology among them advanced molecular technology such as those such as omic analyses, which have achieved a better lacrimal characterization. These analyses have contributed to the differential identification of different molecules that may play an important role in the diagnosis, monitoring and/or treatment of eye and systemic diseases. The purpose of this article is to describe the different characteristics of the tear fluid as well as the possible candidates for biomarkers of mainly reported eye and systemic pathologies.
